Self-excited continuous periodic mechanical vibrations of compressor, fan and pump mainly have an effect on refrigeration equipment (water-cooling refrigerating machines (chillers), autonomous central air-conditioners, condensing units, compressor and receiver units and others), operated in stationary conditions.

For example, in ship conditions, pitching and rolling motion, and vibration of main power unit, propellers and others, exert influence on refrigeration equipment operated on sites, liable to mechanical effects. And in emergency situations there are impact actions. Continue reading →
